Metastability and hysteresis in the low frequency dielectric response of the charge-density wave in K(0.3)MoO(3).
01 January 1986
We have found in recent studies that a great deal about the dynamics of Charge Density Wave (CDW) behavior for materials in which the CDW can be depinned from the lattice can be learned by investigation of the dielectric properties. The study concentrates on a temperature range where metastable CDW states dominate the long time behavior. The results include a characterization of the low frequency density of states of the metastable CDW through measurement of epsilon(omega), as well as the thermal history and electrical history dependence of the static dielectric and conductive responses.
